I hate handicapping myself but I noticed that I did better when I was working on my Art of War and Cherry Blossom camos. I did them both at the same time and I was playing with no perks and with a vanilla weapon. On the three weapons I got to gold, I am surprised that my KD never dropped and it even increased while doing those challenges. I was forced to think every move I make and that made me play even better than usual.
Depends who I'm playing against.
Against experienced players that I've come across before, I'll always use some sort of "tryhard" class but against the more casual player, I tend to try out different weapons (i.e. shotguns or pistol only etc).
we do the same, for giggles the other day we all played with just executioners
Like it? I love it. In every single CoD game I have played so far (Every one since CoD WaW), I try to search for some of the most unusual classes that will still work. When I do get round to using a proper class setup, I generally do slightly better than players of similar stats to me.
Here are some examples of what abominations I have created over the years
WaW: FG 42 with Double Tap
MW2: FAL Holographic Masterkey
BO1: Mac-11 Rapid Fire
MW3: M60E4 Rapid Fire Steady Aim
In better hands than mine, these guns are monsters, the FAL and Mac-11 particually. The Mac-11 remains my most used gun to date (With Stat checking)
